DO OR OR WINDOW SCREEN WIRING MACHINE.

SPECIFICATION forming part of Letters Patent No. 402,884, dated -May "i, 1889A I Application filed February l2, 1889. Serial No. 299,589. (No model.) v

To a/ZZ whom t may concern,.-

Be it known that I, JOHN H. AUTROBUS, a citizen of theUnit-ed States, residing at Ottumwa, in the county of Wapello and State of Iowa, have invented certain new and useful Improvements in Door and Window Screen Viring Machines; and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon. Y

This invention relates to certain new and useful improvements in machines for wiring door and window screens; and the novelty resides in the peculiarities of construction andthe combinations, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of ref1 erenee marked thereon, form a part of this specification, and in which Figure 1 is a vertical central longitudinal section of a machine constructed in accordance with my invention. Fig. 2 is a top plan of the same. Fig. 3 is a vertical transverse section through the line @c x, with portions broken away and partsremoved'. Fig. 4 is a side view of the driver and portion of the arm, showing the lever and manner of connecting the. same to the head-block or slide of the punch arm. Fig. 5 is a vertical section through the driver and a portion of the arm, showing also the inclined arm for the staples to slide down on. Fig. G is a sectional detail showing the manner of fastening the driver to the arm.

Like letters of reference indicate like parts throughout the several views of the drawings, referring to which by letter'-` A designates a tablel of suitable materia and sizeto suit the work to be performed op it, as shown in the drawings, of such a lengt'i as to accommodate two frames, so that as one is being tacked another may be prepared for the driver. This table is supported upon the legs B', as shown, and is suitably braced by means of the transverse timbers a. Near each end of the table I provide a transverse strip, b, which serves-as a stop for the frames, as shown in Fig. 2, wherein C indicates the frames. t

Dare screw-clamps arranged at suitable points crosswise of the table, and consisting of the screw-rod d, held in place in the longitudinal center of the table by means of the plates cl d2,made to fit a journal turned on said screw-rod, said plates being fastened to the table, as shown,and preventing displacement of the rod. This rod is right and left screw-threaded, as shown, and the clamps d3 are moved in opposite directions simultaneously by turning said rod by means of its hand-wheel D. These clamps are designed to press and holdl the stiles of the frame until the wire is fastened thereon, when by loosening said clamps the stiles or sides of the frame will spring back into their natural p0- sition and draw the wire taut. The side timbers of the table are provided with the tracks E, preferably with inverted-V-shaped upper face, upon which the wheels of the carriage, hereinafter described, run.

At each end of the frame I journal upon suitable supports and shafts a roll of wirenetting, F, with which the frames are to be covered.

G is the carriage, supported upon the] grooved rollers g and designed to, travel'uj lengthwise of the table from the tracksl E. This `carriage is suitably braced, as shown, to give strength thereto, and carries the driver or tacking device, which consists of the driver H, attached to thc carriage by means of the plate h, fitted to the slot h in the arm c', and held thereto by means of the screw j, passed through the bar or plate h into the driver H, and provided with hand-wheel/I, by means of which they are clamped together. The arm c' is attached to the slide 7c by means of the swivel Z, and the slide k is constructed to slide transversely ofthe carriage in Ways or guides k. The driver H may be raised or lowered for different thicknesses of frames by turning the screwj to loosen the plate h, and after being adjusted in the slot h to the desired height it can be there secured by tightening the screw. The carriage is moved lengthwise of the table to tack the lines running lengthwise of the frame; but in tacking the crosslines the carriage remains stationary and the driver is moved back and forth on. its guides transversely of the carriage.

I is the punch, designed to force in the tacks or staples. It is operated by means of the lever J, provided with a suitable handle and pivoted at J at one end to the driver Il', and provided with a slot, m, which engages the pin n, which pin is fastened to the slide o, working in the guides @the handle end of said lever working through the slotted guide K, as shown in Figs. 4 and 5. The lower end of the slide o has connected thereto by means of the removable cap q the upper end of the punch I, as shown in Fig. 5.

L is" the inclined staple-guide, down which the staples are designed to feed by gravity to occupy the space vacated by the punch I as the same is raised by the lever J.

M is a presser-plate provided with the pins m', extended through the lower portion of the driver II, and N is a spring attached near its center to the driver I-I by means of the adjusting-screw n', with its ends bearing on the ends of said pins. As the punch is raised the lower end of the presser-plate is thrown toward the staple-guide and closes the lower end of the space and prevents the st-aples from falling through.

O is a block or plate arranged at one end of the table and movable lengthwise thereof on the guides o", and P is a screw engaging threads in said block and passed through the end cross-bar of the table, and provided with a hand-wheel, q ,by means of which the screw may be turned to move the block back and forth. Secured to the block O is the plate Q, carrying at its inner end the lower portion or bar, R, of the clamp. S is the upper portion or bar of the clamp. The bar R is carried by the sliding bar Q and the bar S by the sliding frame S.

T are cam-levers pivoted on the frame S and carrying at one end said bar S, and provided with the curved slot s, in which works the pin t. One of these clamps is arranged at each end of the table.

The operation is as follows: A frame, C, is placed on the table between the clamps (Z3 and the clamps then drawn together byrurn ing wheels D to clamp the side bars of the frame. The wire F from the roll is then placed over the frame, being irst passed between the clamp-bars Rand S. The molding u is then placed over the wire on the frame,

asshown in Fig. 2, and the carriage G run along on its track to bring the driver over said molding, when, by operating the lever J, the staples are driven into the molding and through the wire into the frame. The carriage is moved along as each staple is driven, and as the cross-rails are nailed the driver is moved transversely of the carriage on its guides. The cross-molding u farthest from the roll of netting is first nailed, and the wire then stretched by turning down the cam-levers T and clamping the wire tightly between the clamp-bars R and S, and then turning the screw P, so as to draw outward the block O. The remainder of the molding is then tacked, and when completed the wire is cut off at the desired point and the carriage moved to the other end of the table to tack-the frame at that end, which in the meantime has been prepared ready to tack.

o is a plate secured to the driver Il by the screws o2 and serves as a guide for the punch l.

.1. In a machine for the purpose described, a table, combined with a carriage movable lengthwise of the table and a driver carried by said carriage and movable on guides transversely thereof, substantially as described.

2. In a machine for the purpose described, a table and a carriage movable thereon, combined with a vertically-adjustable driver on said carriage and movable transversely thereof in guides, substantially as and for the purpose specied.

3. In a machine for the purpose described, the combination, with the table, of the block O, the sliding plate Q, the sliding frame S', and the screw I), the bars R and S of the clamp, and the cam-levers T, substantially as shown and described.

1i. The combination,with the driver, of the finger-plate M, provided with pins extended through the lower portion of the driver, the staple-guide, and the spring N, attached to the driver, with its ends bearing on said pins, substantially as shown and described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN Il. AUTROBUS.
